Yeah please stop pushing so hard even if nothing is coming out. I had once very little blood come out when I had pushed too hard, my surgeon strictly asked me to never repeat it.
Somethings you can do at home to cure constipation is take a light laxative like black coffee, pysillium husk with a glass of milk ( believe me this one is the best ). Relax your butt everytime you sit on the seat let the pressure to go build up without trying to push. I sometime sit in weird yoga poses to get evrything out without having to push. Take deep breaths everytime you think you have to push.
I hope you find these a little helpful.
